1 Claim.

The. object ofthe present/invention is to provide an inexpensive, strongand serviceable extension table of a special'type, in which a centralframe is supported by a pedestal arrangement which"may-consist of legmembers, the frame including longitudinal and parallel frame barswhich-are held in fixedposition during the extension and retraction oftable top members, in combination with two extensible table topmembers,each carried by a pair of metal slides which engage metallicangle bars secured to the pedestalframe and forming part thereof.Extension top members conceal, when they are closed, two

transversely extending extension leaf sections, each section carrying askirt to conform with the skirted margin of the primary leaves of thetable, and the two extension leaves being so associated with opposed camplates carried by the pedestal as to'b'e reversely movable to upperposition in line with'the primary table top members or to lower positionbelow said members, at will.

The invention will be described with reference to the accompanyingdrawings, in which Fig. 1 is a plan view of a table in closedpositionand embodying one form of the invention;

ward movement it will lie in the same horizontal plane as the firstmentioned extension leaf section;

Fig. 6 is anisometric view of the first form of the structure in itposition as shown in Fig. 4;

Fig. 7 is a view similar to Fig. 6 showing the elements in the positionof Fig.

Fig. 8 is a top plan view of the first form of the invention showing theprimary leaf supportingmembers .which slide directly thereon;

'Fig. 9is a bottom view of a second modified form of the inventionshowing the primary leaf members in spaced-apart open positionpreparatory to moving the extension leaf sections into operativeposition;

Fig. 10 is a bottom plan view of the modification of Fig. 9 but showingthe primary leaf members in closed position; and

Fig 11 is a vertical sectional view taken on the line |l-|| in Fig. 10.

Referring to the drawings, I have shown, particularly in Figs. 1 to 3inclusive, a first form of the invention comprising a table consistingof the primary leaf members I, Ix, and extension sections 2, 2x. Thetable is supported by a pedestal, which, in the present embodiment,consists of fourlegs 3 (two being shown in the drawing at 2) 'andthelegsi may be rigidly connected pose.

(Cl.c311--48) by cross tubing or bars 4. Thetop of the pedestal-is aframe assembly consisting of the parallel and longitudinally'extendingangle bars 5, and the transverselyextending connecting bars 6.

The connecting bars '6 (hereinafter termed cam bars) are each formedwith a lower cam slot Tand an upper cam slot 8, as to each cam bar 6.The lowercamslot receives the stud (indicated bydotted'lines) 9 ofa'bracket arm It attached to the lower base of extension leaf section 2.The cam slot 8 of each cam bar 6 receives the stud l2 'of a bracket I3secured to the under face of extension leaf section 21:.

Each primary table top member is secured to the opposed angle slide barsH, which, as shown particularly in Figs. 4 and 5, are inter-hooked withthe bars 5 *so as to slide thereon. When the sliding movementis'continued to the position of Figs. 6 and Atheextension leafsectionsare "exposed.

When the primary table top or' leaf members are'in closed position,thesectional leaves 2 and 2m willbe' concealed, their position being asshown inFig. '4. 'In suchposition they are supported by brackets orstuds, as described above, and also bylsupporting brackets l5, as shownin Fig. 4. In "the first movement, in order to raise and extend theextension leaf sections, section 23: is raised and moved'outwardly fromthe position of Fig. land Fig. 5. Thereupon the extension leaf section!is raised and moved outwardly, first to the position of Fig. 5, and thenin continued outward. position untilthe leaf lies horizontally and inabutment with extension leaf 2r. In the complete outward movement ofextension leaf section-'2, its inner edge is spaced from that ofextension leaf section '23:. Therefore the cam slot .1, in each of theopposed cam bars 6, is formed with an inwardly directed and overhanginghorizontal extension Ix. This enables extension leaf section 2- to bemoved inwardly so that its studs will rest upon the horizontal lowerwall of the overhanging slot area and. also the inner edge oflleafsection 2 will abut that of leaf section 2x. It will be noted that theparallel angular frame members-5 arereinforced by transverselyextendingrigid connector members I8 and the table legs may besecureddirectly to member It as by bolts throughthe apertures indicated I9.Primarytable top members may be secured by screws or other fasteningdevices directly to the slides -l I, whichare apertured. as at2ll forsuch pur- Also, as indicated in the drawings, the transverse margins ofthe primary table top members may be provided with pins and sockets,

the sockets being indicated at 2| and the pins at-ZZ-fOrinter-engagementwith themselves and .also with'theextension leaves which are likewise beemployed.

:Referringnowto Figs. 9 to 11 inclusive, whereangle bars 33, 34.

in is shown a modified form of the invention, the reference numeral 3|indicates generally a rectangular frame comprising two spaced horizontalmembers 32, 32. Rigidly secured to the members 32, 32' are a pair oftransverse horizontal As best shown in Fig. 11, the angle bars 33, 34are each formed with a downwardly depending portion 33', 34 and ahorizontally-extending flange portion 33", 34" respectively. Ahorizontally-extending brace member 35 is secured at its opposite endsto the lower portions of the downwardly depending sections 33', 34' anda pair of supporting brackets 36 (only one being visible in thedrawing), similar to the supporting brackets described above withrespect to the first modification, are secured at their opposite ends tothe members 33, 34. It will thus be seen that the members 32, 32', bars33, 34, and brace elements 35, 36 together comprise a rigid rectangularframe 3|.

The reference numerals 38, 39 indicate two primary table top sections. Apair of spaced horizontal slide members 40, 4| are secured at theirleft-hand ends to the undersurface of the table top section 38 by meansof the screws 42 or other suitable means. The opposite ends of theslides 40, 4| project outwardly beyond the straight side edge 42 of thetable top section 38. A second pair of slides 43, 44 are secured attheir right-hand ends to the undersurface of the table top section 39and have opposite ends projecting from the table top section 39 towardthe table top section 38. The slides 40, 4|, 43, 44 are slidably mountedwith respect to the members 32, 32' of the frame 3| in the same manneras described above with respect to the first modification. The ends ofthe bars 33, 34 are provided with slots 46 through which rivets 41extend. The ends of the rivets 41 are secured to the slides 40, 4|. Itwill thus be seen that the frame 3| is slidably mounted with respect tothe slides 40, 4| for limited movement in a direction parallel to theslots 46 and team extent limited by lengths of the slots 46.

The downwardly depending sections 33' 34' of the angle or cam bars 33,34 are provided with a cam slot arrangement adapted to slidably androtatably support the extension leaf sections 49, 50. The latter areprovided with brackets 5|, 52 having studs slidably mounted within thecam slots in the same manner as described above with respect to thefirst modification. Adjacent the straight edge 54 of the table topsection 39 and on the undersurface thereof are mounted a pair of stopmembers 55, 56 having downwardly depending lugs 51. The lugs 51 areadapted to abut against the upper inner surface 341: of thevertically-extending section 34.

The operation of this second modification will now be briefly described:In Fig. the table is shown in the closed position with the table topsections 38, 39 abutting at their respective straight edges 42, 54. Toopen or extend the table, the section 39 is grasped and moved outwardlyto the right as viewed in the drawing. This will cause the slides 43, 44to slide relative to the frame 3| and the slides 40, 4|. When the tabletop section 39 and the slides 43, 44 approach the outermost positionshown in Fig. 9, the lugs 5'! of the stop members 55, 56' will abutagainst the upper inner surface 34a: of the angle bar 34 so as to movethe entire frame 3| to the right along with the table top section 39until the left-hand ends of the slots 46 abut against the bolts 41, asshown in Fig. 9. The leaf extension sections 49, 50 may then be movedoutwardly and upwardly into operating position in the same manner asdescribed above with respect to the first modification. It will be notedthat the pins 58 on the left-hand edges of the leaf extensions 49, 50will then be spaced from the straight edge 42 of the table top section38. Similarly the pins 59 of the table top section 39 will be spacedfrom the right-hand edges 60 of the leaf extension sections 49, 50.After the latter have been moved upwardly into operative position so asto be in alignment with the table top sections 38, 39, the table topsection 39 is then moved to the left so as to cause the pins 58 to entersockets (not shown) provided in the straight edge 42 of the table topsection 38, and also to cause the pins 59 to enter sockets provided inthe right-hand edges 69 of the leaf extension sections 49, 50. The tablestructure will then be in completely assembled operative arrangement.

It will thus be seen that by the suitable location of the stop members55, 56 and also the slots 46 and bolts 41, the proper spacing betweenthe table top sections 38, 39 and the leaf extension sections 49, 50 isprovided automatically by merely one simple outward movement of thetable top section 39. After this spacing has been obtained and the leafextensions moved to operative position, the table top sections 38, 39and the leaf extensions 49, 50 may be quickly brought together intoassembled abutting relation by merely sliding the table top section 39 ashort distance to the left toward the table top section 38.

It will be understood that various modifications may be made in the formof arrangement of the elements constituting the embodiments herein shownand described without departing from the spirit of the invention, what Iclaim and desire to secure by a patent being as follows:

In extension tables the combination comprising a pair of spaced membersand a pair of spaced bars secured to said members and extendingtransversely thereof so as to form a rigid rectangular frame, two pairsof spaced slides on and adapted to co-act with said members by slidingmovement, each pair of said slides supporting a horizontal table topsection, a pair of sectional leaf members, cam means for slidably andpivotally supporting said leaf members on said bars, means for limitingthe relative sliding movement of the frame with respect to a first pairof said slides, and stop means fixed with respect to the second pair ofthe slides and cooperable with the frame for moving the latter in adirection away from the table top section supported by said first pairof slides when the second pair of slides is moved outwardly in saiddirection.
